I am reasonably certain my next project is gonna be a big AR. This is the beginning, I know there are several different variations of the "AR-10, but that's about all I know. Other than it will be in 7mm SAUM, it will have a heavy 28 or 30 inch barrel, and of course accuracy is the most important attribute. (Disclaimer) I am not now, nor do I plan to shoot "1000 yard bench rest competition." So all you bench rest types, go find another thread to unleash your negative rhetoric on. With that being said, any helpful advice will be greatly appreciated. What I have in mind is a rifle capable of taking any antlered critter in North America at extended ranges.
